WVILLIAM D. SOHUYLER, OF NEW YORK, N. Y.

DRAIN-PIPE CONNECTION FOR WASH-BOWLS, WATER-CLOSETS, dc.

SBECIPICATION forming part of Letters Patent No. 337,445, dated March 9,1886.

Application filed March 30, 1885. Serial No. 160,696. (No model.)

To aZZ whom it may concern:

Be it known that l, WILLIAM D. SoHUYLER, of the city, county, and State of New York, have invented certain new and useful Improvements in Drain-Pipe Connections for Wash-Bowls, Water-Closets, &c., of which the following is a full, clear, and exact description.

This invention relates to drain-pipe connections for wash basins or bowls, water-closets, bath-tubs, and other like structures and devices; and it consists in certain attachments, novel constructions, and combinations of parts, substantially as hereinafter described and claimed, whereby escape into the apartment or apartments in which the wash bowl or bowls, &c., are situated of sewer or other injurious odors or gases is effectually prevented and leakage of the drain-pipe or its connections is readily detected.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a plan view of a washbowl with hot and cold water faucets and having my invention applied. Fig. 2 is a vertical sectionof the same on the line 00 x in Fig. 1; and Fig. 3 is a diagram or skeleton view in elevation of the invention as applied to a wash-bowl, bath-tub, and sink, on different floors of a building.

Referring in the first instance more particularly to Figs. 1 and 2 of the drawings, A indicates a wash bowl or basin, to which hot and cold water may be supplied by the usual or any suitable pipe-connection from faucets B B, and which is provided with the customary chained stopper, 0, for retaining the water in the bowl when in use. Each of these supply valves or faucets may be opened when required by pressing down on a screw-nut or button, 1), adjustable on a screw-stem or upright, c, and arranged to bear down on the one arm of a lever, D, having its fulcrum at d, and connected with thevalve-stem e of the faucet, said lever automatically operating in a reverse direction to close the valve when pressure is taken off the button b, and which closing is effected by a weighted plunger-valve, E, or plug of sufficient weight, attached by a chain, f, or other suitable connection to the back arm of the lever D. The means, however, for opening and closing the faucet-valve may be varied, it only being desirable to connect the weighted plunger-valve E with them, so that when the faucet or supply-valveis opened said valve E will also be opened. Both of the faucets B B, where two are used, are similarly connected with the valve E, as shown in Fig. 1. The plungervalve E is arranged to work in a barrel or case, F, its stem 9 extending upward and having a flexible connection, f, with the lever D, as shown and said valve E when closed bearing on a seat, h, to close a lower outlet, 2', which connects by a trap branch pipe, G, as shown in Fig. 3,with the waste or drain pipe H, that leads to the sewer. The barrel or case F is connected above the valve-seat h with the discharge-pipe I from the bowl A, or other receptacle, and when down the plunger-valve E I may also close the discharge-pipe I; but when said valve is-raised or opened and the stopper 0 is removed, then the soiled or standing water in the bowl is free to run off through the outlet t and connection G to the waste ordrain pipe H. The discharge branch pipe I it is proposed to connect at oneside with the valve box or case F, which has the trap G attached to it, so that as the water enters the trap it will have a whirling or circular movement, for the purpose of washing the seat h of the valve free from any foreign substance that might lodge on it and interfere with the closing of the valve E. By the connection of the plunger-valve E with either faucet B or its operatinglever D, then on opening the faucet B the valve E is also opened, and on withdrawing the stopper 0 from its closure of the orifice in the bottom of the bowl the bowl is or may be rinsed or cleared, and on replacing the stopper 0 the bowl will be supplied with water for use, as required. When, however, the faucet B is closed, the plunger-valve E also automatically closes and shuts off sewer or other gas from passing from the drainpipes up into and through the bowl, so that after the bowl has been used and its contents discharged there is no chance of escape of sewer or other gas into the apartment, even should the hand-stopper G be removed. The stem 9 of the valve E is arranged to pass up through orby a lock, J, which is shown in the form of a screw-gland, that in the normal position of] as affected by evaporation or from any other the parts is raised, but which may be screwed down so as to bear on a projection or collar, k, of the stem 9, and so hold the valve E permanently closed. This latter provision will be found of great service on leaving the premises for any length of time vacant, as it will then secure in a locked manner the prevention of escape of sewer-gas, &c., into the building, and by the connection of the valve E-with the faucet it will also serve to prevent the opening of the faucet and supply of water to the bowl. By making the valve E of sufficient weight it will not only serveto automatically close con nection with the drain-pipe, but also to close the faucet when relieved of opening pressure. The traps G, when used, will also be an additional protection against the escape of sewer-gas into the apartment; but main reliance in this respect is placed upon the automatic valve E. The same action takes place whether the receptacle for the waterbe a washbowl, A, a water-closet, a bath-tub, A, or a sink, A, on different floors of a building, as shown in Fig. 3, and whether the valve E be connected with one or two faucets.

To detect leakage in the drain-pipe H or its t connections G below the valves which control the discharge into the drain-pipe from the different vessels or structures to which water is admitted by the faucets, as well as to afford a still further protection against the escape of sewer-gas into the apartments containing said vessels or structures when the building is not occupied, I provide the drain or waste pipe H below the lowest floor of the building to which water is supplied, or between such place of supply and the sewer, with an independent hand shut-off valve or stopcock, K. To detect leakage it will only be necessary to close said stop-cock and to fill the drain-pipe for its full height above it with water, the valves in such case being kept closed. This will determine leakage in the drain-pipe H or its connections G throughout the whole height of the drain-pipe above the stop-cock; and it also admits of any suitable deodorizing material being retained in the water in the waste pipe above the hand shut-off valve K to more effectually contribute to the healthy condition of the drainpipe and its connections.

In this invention it is necessary to distinguish between a mere plugvalve in a wastewater fixture and the plug trap-valve E, attached by a detachable or flexible connection to the operating lever or levers of one or more supply-valves, B, in such manner that it is forcibly worked or opened when either of said supply-valves is opened for the purpose of drawing water therefrom. Furthermore, by using a weighted plug trap-valve, the weight of said valve is sufficient to close it tightly on its seat whenever it is not positively held open by its connection with an opened supplyvalve. Another peculiarity is, that said trapvalve is independent of the action of the water cause, said valve being both forcibly opened by substantial means, and so that such operation is synchronous with the opening of either of the supply-valves, and closed positively by weight acting consentaneously with the closing of the supply valve or valves, suclroperation of opening and closing of the plug trapvalve being in no wise influenced by the quantity of water in the basin or other fixture; also, the arrangement or connection is such that the plug trap-valve may be operated independently of the supply-valves for the purpose of emptying the basin speedily when required. Again, by means of the lock connected with the stem g of the trap-valve and its cylinder or casing and valve-seat, said valve is forcibly closed and retained in or on its seat, and, as hereinbefore described, the supply-valves are or may be locked and their operation controlled. This locking of the valves secures more perfect protection against sewer-gases and poisonous germs at night, also closes the watcufixtures indefinitely in unused rooms or during the absence of the occupants of the building or when it is unoccupied. lhirthermore, by the forcible retention of the plug trap-valve upon its seat, a substantial sealed closure of the upper ends of the otherwise opeu waste-water pipes may be secured, in connection with their closure by a handvalve at the sewer terminus of the waste or soil pipe, for the purpose of filling the wastewater pipes with water for testing and cleaning purposes, all as more or less hereinbefore referred to.

One part of the invention relates to appliances in which a trap-valve worked simultaneousl y with one or more watersupply valves or independentiy of them is used, and consists in certain or special appliances of the kind.

I do not claim drain-pipe H, with its valve K, in this application, intending to make the same the subject of a separate application.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the supply valve or valves of the water fixture or structure and its discharge and drain pipes, of a hand trap-valve connected for joint operation with said supply valve or valves, and an adjustable locking device applied to said trap-valve and connected with the supply valve or valves, whereby both the supply valve or valves is or are held shut and the hand trap-valve is forcibly and permanently closed, essentially as shown and described.

2. The combination, with the dischargepipe of a wash-bowl, water-closet, or other like water convenience or structure, its discharge-pipe and waste-water drain or soil pipe, and with the water-supply valve or valves to said structure, of the weighted plug or plunger trap-valve having an upwardlyprojecting stem, the flexible or chain connecoperating-levers D, the self-closing plug or 10 tions between said trap-valve and the supply trap valve E and its ease F, the flexible convalve or valves, and an adjustable lock apnections f, and the adjustable lock J, subplied to the stem of the trap-valve and stantially as and for the purposes herein set 5 adapted to forcibly close said valve when reforth.
